usally when they shed the skin in there nose will come out wit it. but there is still a hole for the air to pass. this ones skin was completely solid and the air couldnt pass causing him to have to breath through his mouth all the time.
i think they like the tooth brush. u know when they go in the water and scratch like dogs at there heads and eyes?

it did bleed slightly not even a drip just barely noticable. it was like his nostrals where growing in permanetly

We had this problem with both our older beardies. For the first few weeks they hardly ate at all. Could it be stress? I know little things like changing the viv lay out can stress them out so going from its original viv to your home could be traumatising.

They do go off their food when they're due to shed although every beardie is different. Have you considered worms? Our male had them recently and he went off his food completly.

Obviously if things dont improve take him to the vet
